Abstract

At 77 K, stimulated emission from n=1 light‐hole excitons in a ZnSe‐Zn0.8Cd0.2Se superlattice is observed and the oscillation mode properties of n=1 light‐hole and heavy‐hole excitons are analyzed. It is noticed that the ZnSe‐Zn0.8Cd0.2Se superlattice with the shorter Fabry–Pérot cavity length d has the larger threshold excitation. The threshold of each mode has been determined using its time delay curve.
